Near-IR speckle imaging of massive young stellar objects
We present near-IR speckle images of 21 massive Young Stellar Objects(YSOs) associated with outflows. The aim of this study is to search forsub-arcsecond reflection nebulae associated with the outflow cavity. Wefind that 6 of the massive YSOs show a conical nebula which can beinterpreted in terms of reflected light from the dusty walls of theoutflow cavity. In all cases, the small scale structures seen in ourimages are compared with outflow indicators found in the literature. Noclear correlation is found between the presence of the reflectionnebulosity and any property such as degree of embeddedness. We also notethat 3 of the sources show close companions, one of them belonging alsoto the sample with conical nebula.Figures \ref{S140SpeckleFig}, \ref{S255SpeckleFig},\ref{Ha101Fig}-\ref{HGL490Fig} and\ref{GL2591SpeckleFig}-\ref{GL5180peckleFig} are only available inelectronic form at http://www.edpsciences.org

MK classification and photometry of stars used for time and latitude observations at Mizusawa and Washington
MK spectral classifications are given for 591 stars which are used fortime and latitude observations at Mizusawa and Washington. Theclassifications in the MK system were made by slit spectrograms ofdispersion 73 A/mm at H-gamma which were taken with the 91 cm reflectorat the Okayama Astrophysical Observatory. Photometric observations in UBV were made with the 1-meter reflector at the Flagstaff Station of U.S.Naval Observatory. The spectrum of HD 139216 was found to show a strongabsorption line of H-beta. The following new Am stars were found:HD9550, 25271, 32784, 57245, 71494, and 219109. The following new Apstars were found: HD6116, 143806, 166894, 185171, and 209260. The threestars, HD80492, 116204, and 211376, were found to show the emission inCaII H and K lines.

Third preliminary catalogue of stars observed with the photoelectric astrolabe of the Beijing Astronomical Observatory.
